Abstract :
The gas pipe in shield is one of the key parts of the long distance pipeline projects. It brings a great deal of uncertainty and risk factors for pipeline pigging operations. Paper establishes the finite element model, analyzes pig pigging and the impact over bending. Under the operating parameters of the pipeline pigging operations are given, paper develop the dynamic simulation model, analyzes the relationship among pipeline pressure, foam pigging speed and pipe stress. Through analyzing the motion law of acceleration and velocity, paper discusses the security of pipeline pigging operations.
